Fix YYYY date format rendering as "Jan YYYY" in HTML output

[Copilot]

Fixed an issue where dates provided in YYYY format (e.g., "2023") were being rendered as "Jan YYYY" instead of just "YYYY" in the HTML output.

Problem

When startDate, endDate, or other date fields were provided in YYYY format, the dayjs library would default to January 1st of that year and format it as "Jan YYYY" when using the 'MMM YYYY' format. This affected all sections that display dates:

• Work section: "2023" → "Jan 2023 – Present" ❌
• Awards section: "2014" → "Jan 2014" ❌
• Publications section: dates not displaying correctly ❌

Solution

Enhanced the dateRange and date functions in the EJS template to:

1. Detect YYYY-only dates using regex pattern /^\d{4}$/ and display them as-is
2. Handle YYYY-MM format using regex pattern /^\d{4}-\d{2}$/ and format as "MMM YYYY"
3. Preserve existing behavior for YYYY-MM-DD and other formats
4. Fix Publications section to use the correct releaseDate field name

Result

All date formats now render correctly:

• YYYY format: "2023" → "2023" ✅
• YYYY-MM format: "2014-10" → "Oct 2014" ✅
• YYYY-MM-DD format: "2022-01-01" → "Jan 2022" ✅

Testing

Updated sample data to include various date formats and verified the fix works across all sections:

• ✅ Work: "2023 – Present" (was "Jan 2023 – Present")
• ✅ Education: "2011 – Jan 2014" (mixed formats working)
• ✅ Awards: "2014" (was "Jan 2014")
• ✅ Publications: "Oct 2014" (YYYY-MM format working)
• ✅ Volunteer: Existing dates work correctly
• ✅ Projects: Existing dates work correctly


The screenshot shows the corrected date formatting in the Work section ("2023 – Present") and Awards section ("2014") without the unwanted "Jan" prefix.

Fixes #18.
